A great addition to your list is HIDDEN POCKETS.

Your velcro is great for front pockets but hidden pockets are on the INSIDE of your shorts/pants so essentially nobody can get into them unless you go from the inside.

Great for larger amounts of cash, backup credit/debit cards, passports etc.

I have the second version and they are amazing and great for peace of mind.
